Laurasia

Laurasia was the tenth continent to form on earth. Laurasia served and as the prime continent for the entire Mesozoic and the early Cenozoic. Laurasia is the continent that hosted the dinosaurs, and most dinosaur fossils came from this continent. Laurasia looked a little like today’s continents, with some things different here and there. When it broke up, it created the 7 continents, along with Pangaea, which helped as well. Laurasia formed around 250-260 million years ago in the late Permian, and broke up around 55-60 million years ago in the Paleogene Period.
